 Structure principle 
 Level gauge according to the buoyancy principle and the principle of magnetic coupling work. When the measured level in the container movements, the dominant tube level gauge also will lift the float, the permanent magnet in the float passes through the magnetic coupling to the scene indicator turned red column driver switch 180 °, when the liquid bits increases, the column turned from white to red, when the liquid level when the column turned from red to white, indicator of red and white for the container industry is located in the actual height of the media level, in order to achieve level instruction . 

 Scope 
 UHZ-517C16-type corrosion-resistant magnetic level gauge turned column for hydrochloric acid, sulfuric acid and other inorganic measurement of corrosive liquids, the use of imported high strength with the metal close to, especially in PPR's unique insulation, making the product suitable for outdoor water tank level measurement, the event will not freeze in winter inside. 
 Suitable for aggressive media level measurement. In addition to the instructions of the transmitter can be equipped with remote, alarm (control switch), the detection range. Indicates new, intuitive readings, eye-catching, observing the direction indicator can be changed according to the user point of view. Measurement range, from tank height restrictions, indicating complete separation of institutions and the measured medium, thus sealing, high reliability, safe to use. Simple structure, easy installation, low maintenance costs.
